When I was knitting about 30-35 yrs ago, I started sewing them together thinking they would make a nice crazy quilt/patchwork type blanket. I think that project is still stuffed in the back of my closet somewhere, totally abandoned when I stopped knitting.

When I started knitting again about 5 years ago, I don't do so many projects that I need to swatch. I knit mostly socks, purses, dishclothes, mostly small things that I don't swatch for.

I love the Barbie blanket idea! I've never done a swatch (eek!) but then again, I really only knit blankets and scarves with a pair of socks thrown in here and there. I'm guessing you could seam up the sides of your swatch and make sachets, soap savers, or coin purses. Thisproject on Ravelry encompasses the general idea. Or maybe felt some of the swatches and used them as coasters!
